For several hours I tried to sync my small music library to my Ipod Classic 160gb. Sometimes when it would freeze, I would get error 50. Other times, error 63. After doing some searches on Google, I learned about diagnostic mode.



It came up with this:


Retracts: 9

Reallocs: 6760

Pending Sectors: 40

PowerOn Hours: 45

Start/Stops: 15012

Temp: Current 23c

Temp: Min 10c

Temp: Max 58c


I did a format and tried again. It came up with this:


Retracts: 10

Reallocs: 6976

Pending Sectors: 40

Poweron Hours: 45

Start/Stops: 15019

Temp: Current 31c

Temp: Min 10c

Temp: Max 58c


Is it time to give up on this Ipod and move on? I did squeeze about 3 good years out of it. But if there is any good quick "fix" I am all ears!

    Hello nekromanitik,


    It sounds like you are getting error 50 or 63 when trying to sync your iPod classic to your computer.  I found some steps you can take when you get error 50 when syncing:


    Error 13, 14, 35 and 50 (or -50)

    These errors are typically resolved by performing one or more of the steps listed below:

    1. Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
    2. Put a USB 2.0 hub between the device and the computer.
    3. Try a different USB 30-pin dock-connector cable.
    4. Eliminate third-party security software conflicts.
    5. There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
    6. Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
    7. Try to restore from another known-good computer and network.
